Humans have 46 chromosomes. But what about other animal species ?

There are surprisingly few comparative lists of chromosome numbers to be found on the internet. I admit : it does not make a lot of sense. What would be the scientific value of that ?

Just out of curiosity I searched a bit and as far as I know below is the only list of animal species with 46 chromosomes :

- Humans (Homo sapiens)
- Muntjacs (Muntiacus reevesi)
- Black rat (Rattus rattus) , but not all of them have 46
- European hare (Lepus europeus)
- Merriam’s ground squirrel (Spermophilus canus)
- Southern short-tailes shrew (Blarina carolinensis)
- Mountain beaver (Aplodontia rufa)
- Beach vole (Microtus breweri)
- Nilgai (Boselaphus tragocamelus)
- Kirk’s dik-dik (Rhynchotragus kirki)
- Grey vole (Microtus arvalis)
